Проблема прийняття рішень у гібридних моделях авторизації для розподілених інформаційних систем

Abstract

Modern distributed information systems are characterized by such features as a large number of users and services, geographical distribution of components, dynamic access policies, and different levels of trust in system nodes. In this work, a model for access decision-making in a hybrid authorization system is proposed, based on the verification of user roles, the analysis of user and resource attributes, and the assessment of contextual access risk
